My sourdough starter died after I forgot it in the car for 3 hours
Last Saturday I ran errands in Austin and left my starter on the passenger seat. It was 94 degrees and by the time I got back it was bubbling weird and smelled like vinegar and old socks. I tried to feed it twice but it never recovered, so I tossed it and started a new one from scratch on Monday. Anyone else had a starter go bad from heat or did I just get unlucky with that batch?
Lost mine the same way last summer, forgot the jar in my truck bed after a farmers market run and it cooked at like 100 degrees for a whole afternoon. What saved the next batch was keeping a backup in the fridge, just a little spoonful dried on parchment paper and sealed in a ziplock. Sounds weird but you can revive the dry flakes with warm water and flour weeks later, no problem. Now I always pull off a bit before it goes anywhere with me, because cars turn into ovens down here. Heat that high basically kills off the yeast and lets the bad bacteria take over, which is that vinegar sock smell you got. Sorry about your starter, but the dry backup trick has saved my bread more than once.
